YIELDABLE SUPPORT FOR FURNITURE.

Specification of Letters Patent.

Patented Apr. 9, 1912.

Application filed November 15, 1909. Serial No. 528,071.

To all whom it may concern:

Be it known that I, JoIIN Minutes, a subject of the King of Hungary,residing at Glen Carbon, in the county of Madison and State of Illinois,have invented certain new and useful Improvements in Yieldable Supportsfor Furniture, of which the following is a specification, referencebeing had therein to the accompanying drawing.

This invention relates to yieldable supports for furniture, and moreparticularly to a support adapted to be used in connection with stools,chairs and pieces of furniture adapted to support persons.

The primary object of my invention is to provide the legs of a stool orchair with novel sockets for yieldably supporting the stool or chair,thereby cushioning the stool or chair when carried over irregularsurfaces.

Another object of this invention is to provide a yieldable socket thatcan be advantageously employed in connection with the stools used bymotormen upon trolley cars, the yielda-ble sockets cushioning the stoolsto that extent that the motorman is not subjected to vibrations whensitting upon the. stool during the movement of the car.

ith these and such other objects in view as may hereinafter appear, theinvention consists of the novel construction, combination andarrangement of parts to be specifically described and then claimed.

Reference will now be had to the drawing forming a part of thisspecification, wherein there is illustrated a preferred embodiment ofthe invention; but it is to be understood that the structural elementsthereof can be varied or changed without departing from the spirit andscope of the invention.

In the drawings :Figure 1 is a side elevation of a stool provided withyieldable supports or sockets. Fig. 2 is an enlarged vertical sectionalview of one of the supports or sockets. and Fig. 3 is a verticalsectional view of a modified form of support or socket.

In the accompanying drawing. the reference numeral 1 denotes a sleeve ortubular body adapted to be titted upon the lower end of each one of thelegs or supports 2 of a stool or piece of furniture. The upper end ofthe sleeve or tubular body 1 can be socured upon the legs or supports 2by rivets 3 or other fastening means. The lower end of the sleeve ortubular body 1 is exteriorly screw threaded, as at 1 to receive a cap 5having a central vertical opening 6. Slidably mounted in the opening 6and extending into the sleeve or tubular body 1 is a rod 7 having theinner end thereof extending into a recess 10 provided therefor in thelower end of a cylindrical head or piston 11, which is slidably mountedin the sleeve or tubular body 1. The upper end of the rod 7 is rivetedor otherwise secured in the recess 10, as at 12.

The lower end of the rod 7 is provided with a head 13 having a dependingexteriorly screw threaded shank 14 upon which is screwed a cylindricalbody or foot 15.

Interposed between the lower end of the cap 5 and the head 13 andencircling the rod 7 is a coiled spring 16 preferably made of aresilient rod or strip of metal which is rectangular in cross section.

The sleeve or tubular body 1 adjacent to the leg or support 2 isprovided with a small opening 17 to allow air within the sleeve ortubular body 1 to exhaust during an upward movement of the cylindricalhead or piston 11.

In assembling the various parts of the yieldable support or socket, thespring 16 is first positioned upon the rod 7. The cap 5 is then placedupon the rod and then the end of the rod secured in the head or piston11. The head or piston 11 can then be placed in the sleeve or tubularbody 1. and the cap screwed upon the lower end of said sleeve or body.The upper end of the sleeve or body can then be. fitted upon the leg orsupport 2 and secured thereto.

It is obvious that the spring 16 will normally cushion a downwardmovement of the leg or support 2 and thereby prevent the leg or support2 from being unduly jarred by a movement of the floor or base supportingthe piece of furniture equipped with the yieldable sockets.

In Fig. 3 of the drawing. I have illustrated the tubular body 1 providedintermediate the ends thereof with an annular interior collar 18 and therod T which ex tends into the tubular body I is provided with a collar19. l lncircling the upper end of the rod 7 between the collar 19 andthe collar 18 is a coil spring 20, serving the same purpose as thespring 16. In this modification the cylindrical head or piston 11 isdispensed with.

Having now described my invention what I claim as new, is

A yieldable support for furniture legs comprising the combination withthe leg, of a tubular member having a part of its upper end surroundingand fixedly secured to the leg, said member further provided inproximity to the lower end of the leg with an opening of small diameter,a cap mounted upon the lower end of said member, a piston mounted insaid member and normally engaging the cap, a shiftable rod eX- tendingthrough the cap and secured to the piston, a head carried by the outerend of the rod, and a coiled spring surroundin said rod and interposedbetween the lower end of the cap and the said head.

In testimony whereof I aliix my signature in the presence of twowitnesses.
